JOHN WV. HARRINGTON, OF AUGUSTA, GEORGIA.

COTTON-SEED CLEANER.

SPECIFICATION forming part of Letters Patent No. 751,639, dated February9, 1904.

Application filed June 22, 1903.

To all whom it WI/[by concern:

Be it known that 1, JOHN W. HARRINGTON, a citizen of the United States.residing at Augusta, in the county of Richmond and State of Georgia,have invented a new and useful Cotton-Seed Cleaner, of which thefollowing is a specification.

This invention relates to cotton-seed cleaners.

The principal object of the invention is to provide a simple andeffective apparatus for removing from cotton-seed the dust and dirtwhich is ordinarily adherent in varying quantities to the lint attachedto the cotton-seed and which is objectionable partly because it lessensthe value of the lint detached from the cotton-seed by the lintersthrough which it is passed prior to use in manufacturing cottonseed oiland, further, because the accumulations of dust and dirt on the lint ofthe cottonseed are injurious to the saws of the linters through whichthe cotton-seed is passed.

In attaining the object above stated I make use of the construction andcombination of parts of a cotton-seed cleaner hereinafter described andclaimed, and illustrated in the accompanying drawings, forming a part ofthis specification, in which corresponding parts are designated by thesame characters of reference throughout the various views in which theyappear, it being understood that changes in the form, proportions, andexact mode of,

assemblage of the elements may be made without departing from the spiritof the invention or sacrificing the advantages thereof.

In the drawings, Figure 1 is a vertical longitudinal section through theseed-cleaner on the. median line. Fig. 2 is a vertical transversesection through the cotton-seed cleaner on the line 2 2 of Fig. 1.

Referring to the drawings by reference characters, C designatesgenerally the casing of the cleaner, at the top of which is mounted,preferably, a hopper H, through which cotton-seed is fed to the interiorof the casing.

WVithin the casing C is rotatably mounted in bearings 1, at the sidesthereof, a shaft 2, having on one end external to the casing a pulley 3,which is rigidly attached to the shaft. WVithin the casing there arefastened Serial No. 162,680. (No model.)

to the shaft 2 a plurality of heaters L, each consisting of a bar ofmetal having a slight twist approximately midway between the ends andprovided near one end with a concavity 5, adapted to correspond to thecontour of the shaft 3 and having on either side of the concavity 5 anopening for the passage of a securing-screw 6. The beaters 4 arearranged in pairs, as shown, each pair having the twisted endsoppositely disposed and being secured together by screws 6, as abovementioned. The pairs of heaters are arranged so that when the shaft isrotated in the direction indicated by the arrow in Fig. 2 they tend topropel the cotton from the end of the casing under the hopper H towardthe opposite end.

Beneath the beaters i there is secured within the casing C a curvedmetal sheet? of such curvature that the revolving heaters travelthereover without contact with its surface, but pass in close proximitythereto throughout the entire length of the sheet. The sheet 7 isperforated to permit the passage downward out of the casing C of theloose dirt detached from the cotton-seed by the bars 4:, and the loosedirt on passing through the perforations in the sheet 7 escapes to theoutside of the apparatus through an opening 8 in the side thereof bytraveling over the inclined bottom 8, which forms a sort of chute thatextends out to one side of the apparatus, as shown. The curved sheet 7lies in contact with the side of the casing adjacent to the hopper H;but at the opposite side the sheet 7 is spaced from the side of thecasing, so that the cotton-seed forced in that direction by the heatersis caused to pass off the surface of the sheet 7 and down over aninclined surface 9, which terminates a short distance from an inclinedwall or stop 10, against which the cotton seed strikes after passingbeyond the lower edge of the chute 9.

At the lower end of the wall 10 is provided a box 11 to receive solidparticles too large to pass through the openings in the sheet 7 and tooheavy to be disposed of in the manner presently to be described. Openinginto the box 11 is a pipe 12 from a blower or fan 13 of any suitableconstruction, which is mounted, preferably, under the casing C anddriven from any suitable source of power. The blast of air introducedthrough the pipe 12 strikes against the inclined wall 10 and spreads outover the surface thereof, but is directed generally upward toward thetop of the wall, where it is spaced, as shown at 12, from the top 11 ofthe box 11, said top l1 acting in the nature of a deflector, as will bereadily understood. Stones and other heavy material too large to beseparated through the screen 7 will pass from the inclined wall 9 ontothe inclined wall 10 and thence through the opening 12 into the box 11,from which they may be afterward removed. The blast of air strikingagainst the cotton-seed which is discharged upon the wall or stop 10from the chute 9 carries it upward over the top of the wall 10 and intoa hood or receiving-chamber 15, from the upper part of which extends anescapepipe 16, as shown. The hood or receivingchamber is provided alsowith a door 17 by means of which entry to the interior of the hood orchamber may be had when desired; but the door is normally kept closed,and the only other openings communicating with the receiving-chamber arethose through which the air enters from the blower 13 and the escape-pipe 16. Consequently the cotton-seed the dirt upon which has beenloosened or detached by the action of the beaters A will be forced upover the inclined wall or stop 10 and thrown against the top of the hoodor receiving-chamber 15 and the fine dirt intermingled therewith will beseparated from the lint on the seed by the action of the blast of airand will in great measure be carried out through the escape-pipe 16,leaving the cotton-seed that settles to the bottom of thereceiving-chamber or hood almost entirely free from dust or c irt.

At the bottom of the hood or receivingchamber 15 is preferably provideda conveyer of any suitable type, as the belt conveyer 18, (shown in thedrawings,) upon which the cotton-seed falls after passing over the topof the inclined Wall 10 and by which the clean cotton-seed is carrieddirectly to the linters.

Cotton-seed which is passed through the cleaner as above described, andillustrated in the accompanying drawings, is freed from adhering dustand dirt to such an extent that the value of the lint removed from theseed by the linters is materially increased in Value, and thelinter-saws retain their sharpness and effectiveness for a considerablylonger period when the cotton is previously cleaned by means of acleaner of this form than when introduced directly into the linterswithout cleaning.

Having thus described the construction and use of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. The combination in a cotton-seed cleaner of a casing, a concavescreen near the bottom of said casing, a shaft arranged longitudinallyof said screen on the upper side thereof, a plurality of beaters securedupon said shaft, a discharge-chute sloping laterally beneath said screento a discharge-opening in the side of the casing, an inclined surfacearranged at the discharge end of said screen, a second inclined surfacearranged substantially perpen dicular to the first inclined surface andspaced from the lower end thereof, a trash-receiving box at the bottomof one side of the second inclined surface and spaced a short distancetherefrom, a hood or receiving-chamber at the opposite side of saidinclined surface and an escape-pipe for dust laden air provided in thetop of said hood out of the plane of said second inclined surface.

2. The combination in a cotton-seed cleaner, of a casing, a concavescreen near the bottom of said casing, a plurality of revolving beatersabove said screen, a laterally-inclined discharge-chute beneath saidscreen sloping to a discharge-opening in the side of the casing, aninclined surface. at the end of said screen over which cotton-seedpasses from the screen, a second inclined surface arranged substantiallyperpendicular to the first inclined surface and spaced from the lowerend thereof, a trash-receiver at the bottom of said second inclinedsurface and having a deflecting top spaced therefrom, a blowerprojecting a current of air against the lower portion of said secondinclined surface at an angle thereto, a hood covering the upper end ofsaid second inclined surface and spaced a short distance therefrom, anair-escape pipe in the top of said hood and a traveling apron at thebottom of said hood being arranged in spiral lines and being secured tothe shaft in pairs, of which the two members project in almost directlyopposite directions from the shaft, upon which they are secured by meansof bolts arranged on opposite sides of the shaft and passing throughboth members of the pair of beaters.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

JOHN V. HARRINGTON.
